The World Heart Federation (WHF) reported criteria for the echocardiographic diagnosis of rheumatic heart disease in pediatric patients. One task is to study changes in the mitral valve.


Patient selection: age <= 20 years of age


Pathologic mitral regurgitation – all of the following:

(1) mitral valve regurgitation seen in 2 views

(2) regurgitant jet length >= 2 cm in any view

(3) regurgitant jet velocity >= 3 m/s for one complete envelope

(4) pansystolic regurgitant jet seen in at least one envelope


Pathologic mitral stenosis:

(1) stenosis AND mean gradient >= 4 mm Hg


Morphologic features of mitral valve – total number present:

(1) thickening of anterior leaflet >= 3 mm

(2) thickening of chordae

(3) restriction in leaflet motion

(4) excessive leaflet tip motion during systole
